  @俺がガンダムだ said in LVGL performance problem:

  I applied LVGL on stickc-plus2，with TFT_eSPI's st7789v2 driver.But the refreshing rate is very low (while doing "load screen anim").I know stickc had good performance on drawing screen (by watching the video of M5stick T-Lite Thermal tutorial). And the LVGL also has a good performance through Dial-ESP32-S3 and Din-Meter demonstration video.

  So what is the reason of such low performance. Cound it be the TFT_eSPI library?

  I’ve seen similar issues on the StickC-Plus2. It could be due to TFT_eSPI settings, try increasing the SPI frequency or enabling DMA. Also, check your LVGL buffer config; full buffering helps with performance.

  I'm experiencing multiple issues uploading firmware to the cardputer.
  I'm unable to connect to the cardputer unless I do: "sudo chown 'user' ttyACM0"
  After do this I can verify a connection in m5burner but I can't burn anything if I do it says the following:

  "JavaScript error occurred in the main process"
  "uncaught Exception:
  Error: spawn /mnt/'drive'/'file'/0M5Burner-v3-beta-linux-x64/packages/tool/esptool EACCES
  at Process.ChildProcess._handle.onexit (node:internal/child_process:282:19
  at onErrorNT (node:internal/child_process:477:16)
  at processTicksAndRejections (node:internal/process/task_queues:83:21

  I've also tried running as admin.
  "sudo ./m5burner"
  which returns:
  [1230/051906.244212:FATAL:electron_main_delegate.cc(290)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.
  fish: Job 1, 'sudo ./m5burner' terminated by signal SIGTRAP (Trace or breakpoint trap)

  so then I tried adding no sandbox "sudo --no--sandbox ./m5burner"
  which returns
  sudo: unrecognized option '--no--sandbox'

  I welcome any suggestions that might fix this sour pickle.

  I'm building a MicroPython app on the UIFlow 2.3.6 os for a CoreS3.
  The new m5ui LVGL widgets are wonderful, eg List, Dropdown, that are populated with touch buttons to make the selection. If there are more options than fit in the visible list a scroll bar appears and the list can be dragged. But this is made unusable by the scrolling speed .. I believe due to the animation speed.

  When I load 15 to 20 unattached strings (like with Blockly) the scroll speed is passable at first, but seems to get slower over time. The animation becomes painfully intrusive, until it is taking several seconds to ripple to a halt. I am deep copying the strings to the list, so there's no linkage or processing drag.

  Is there any way to change the animation speed, or turn it off? Or any other workaround suggestions?

  Thanks so much for any advice or suggestions.

  I don't know if this has been answered, and I'll delete it if I find that it has.

  I simply don't understand how I get my CoreS3 back to the main loading screen after I have run an app on it. No combination of buttons seems to work. Any help would be appreciated!
