If none of the scenarios below improve the browsing speed, you may also save a session of a display that is slow to load and send it to us as genome-www@soe.ucsc.edu so that we may provide further guidance.
Drawing the tracks image can become a cumbersome task when too many tracks are enabled and/or if the viewing window is too large. Setting some track visibilities to hide or zooming into a smaller window should alleviate this problem. -Another consideration is to reduce the visibilities of tracks by by setting them to -dense visibilitiy instead of full/pack/squish. +Another consideration is to reduce the visibilities of tracks by setting them to +dense visibility instead of full/pack/squish. That will also speed up the drawing.
Having a large number of custom tracks loaded can lead to a slowdown. However, the slowdown should be minimal unless a large number of tracks are turned on. Custom tracks can be hidden like any other track, or they can also be entirely removed from the custom tracks page.
It is also possible to completely reset the Genome Browser session, which will remove all settings including filters, track order, and all custom data. To do this, click "Genome Browser" > "Reset All User Settings" in the top blue bar menu or
You can accomplish this by using Blat and the Genome Browser Superfamily track. Blat the protein -sequence from the NCBI RefSeq record, then choose the choose the Browser display option to view your +sequence from the NCBI RefSeq record, then choose the Browser display option to view your search results in the Genome Browser window. Set the RefSeq and Superfamily tracks to full display mode. The RefSeq track will contain the entry LIPE, and you will find the corresponding entry ENSP00000244289 in the Superfamily track. Click the Superfamily entry, and then click the Superfamily link on the details page that displays. This will open a browser for the Superfamily site. Click "alpha/beta-Hydrolases" to open the Structural Classification of Proteins (SCOP) page. There you will find multiple families listed under this Superfamily, including the lipase in which you're interested.

Each annotation track in the Genome Browser has one or more database tables associated with it. To find the name of the primary table, navigate to the schema page. You will find the schema page by pressing the "mini-button" to the left of the annotation track display, or clicking the hyper-linked track name in the track controls (below the display). From the resulting description page, follow the "View table schema" link. Finally, on the schema page, you will find the name of the database table near the top of the page listed after the "Primary Table" label.
Historically, NCBI RefSeq coordinates were not directly available for building tracks in the UCSC -Genome Brower. Instead of using coordinates to map annotations, mappings to the reference assembly +Genome Browser. Instead of using coordinates to map annotations, mappings to the reference assembly were conducted using BLAT (BLAST-like alignment tool) alignment methods. This BLAT alignment method has caused some discrepancies from the NCBI RefSeq database. Most discrepancies arise when the BLAT-generated annotations align to multiple regions where the sequence in the assembly is either identical or nearly identical. In essence, by using BLAT to align the sequence, a single transcript could result in matching to multiple novel places across the genome, or alignments of small exons could differ slightly in final coordinates within the region of a gene rich with repeats. BLAT-generated RefSeq track methods are described in corresponding track description pages (e.g., RefSeq track description for hg19).
In 2017, NCBI RefSeq coordinates for hg38 were used for generating non-discrepant RefSeq tracks in the UCSC Genome Browser. This new NCBI RefSeq track in the UCSC Genome Browser displays identical RNA
